what process do plants use to make food
photosynthasis
1 of 27
what is the green pigment in plant cells which allows them to trap the energy in light
chlorophyll
2 of 27
what food do plants make
glucose
3 of 27
what can glucose be stored as
starch
4 of 27
what is iodine used for
testing for starch
5 of 27
what color does iodine turn when exposed to starch
Brown to black
6 of 27
what is elodea
an aquatic plant
7 of 27
how to measure the rate of photosynthasis by measuring the rate of oxygen production by aquatic plants
count the bubbles
8 of 27
how many varibles can be changed in a fair test
1
9 of 27
experemental results can be made more reliable by
reapeating the experement
10 of 27
which facter dose not limit photosyntahsis
dog urine
11 of 27
which axsis does the input variable go on
x
12 of 27
what does % =
change /original x 100
13 of 27
do plants need light to respire and photosynthasis
only photosynthasis needs light
14 of 27
what does respiration do
respiration uses oxygen to realese the energy in glucose
15 of 27
what does respiration produce
water and co2
16 of 27
why do high tempretures reduce the rate of photosynthasis
they denature enzymes controlling photosynthasis
17 of 27
what can be used to show the effects of the limiting factor
a lign graphs showing the rate of photosynthasis
18 of 27
what results do you get by overcoming the limiting factors of photosynthasis
faster growth rate
19 of 27
what are seeds
the product of sexual reproduction in plants
20 of 27
what is germination
development of a seed into a new plant
21 of 27
what is the acronim for requirements of germination
WOW

what does asexual reproduction produces
clones
23 of 27
what is not a natural method of asexual reproduction
taking cuttings of a plant
24 of 27
plants provide food fuel raw materials asthetics and medicines
t
25 of 27
whaT AR THE TOP AND BOTTOM OF THE CELL CALLED
UPPER AND LOWER EPIDEMIS
26 of 27
WHY IS THE UPPER EMIDERMIS TRANSPARIT
BECAUSE IT ALLOWS LIGHT INTO THE MESOPHYLL LAYER
